To {1J/, whom t may concern.

Be it known that I, BENJMIINWOLHAUP- TER,-a citizen of the United' States, and -a resident of Chicago, in the county of Cook and State of-Illinois, have invented certain new and useful Improvements in Tie-Plates and I do hereby declare/that the following is a full, clear,land exact description thereof,

reference being had -to the accompanying drawings, and to the letters of reference' inafter described, and set forth in the pap,-

pended claims. y In the accompanying drawings,yillustrat `in g my invention, Figure 1 is a sectional view takenupon line 1 lof Fig. 2 of a trackrail and tie, together with a tie-plate made in accordance with'my invention. Fi 2-is a plan view of the rail and tie-plate s own in Fig. 1., Fig. 3 is a detail section taken throu h the margin of the rail-flange at the end o' thetie-plate and adjacent part of the tie,'showing a modified forni of construction ofthe tie-plate embodying my invention.

Fig. 4 is a plan view of the construction shown in Fig. 3. Figs. 5 and 6 are views corresponding with-Figs. 3 and 4, showing still another modification in the construction of the tie-plate. Figs. 7 and 8 are still other views corresponding with Figs. 3 and '4 and showing` still another modication inthe con-` struction of\ the tie-plate.`

As shown in said drawings, A indicates the track-rail, and a @the base-flanges thereof.

B indicates the wooden tie on which the rail is supported, C the tielate, and D D D lag-screws or screw-spikes by which the rail is attached to the tie.

it into the tie. The fiange or head d forms Each of the screw- 4spikes D is of common form, having at its an annular downwardlyfacing shoulder which overlaps 'and bearsA againstthe man ginal part of the base-flange a of the rail. The tie-plate C is made generally in a inanner heretofore common--that is to say, it

Ahas in general the form of a lat plate with a v'horizontal top surface forming the rail-seat and provided near one of its ends or at one side of the rail-seat with an elevated rib c, extending parallel with the rail'and shaped to formv an inwardly-facing shoulder against which rests the edge of the base-flange of the rail. The tie-plate provided with a iiange 0,'

as described, is placed beneath the rail witl: the flange in contact with the outer side oi the rail, so that the flange-'serves to resist the tendency'to outward movement in the rail due to the pressure of the anges of the carwheels on the inner side ofV the rail-head.

Said tie-plate C is provided with holesfor the screw-spikes, one 'of which is shown at the left side of Fig. l and there indicated by c.

The tie-plate isshown as provided with holes for .three screw-spikes, two of- .which latter are located. at the outer side of the rail and one at the inner side thereof.

' Now referring to the novel feature in the:

tie-plate to whichmy invention more -particularly relates, said tieplate, as shown ir Figs. 1 and 2, is provided near its end margins and outside of the holes through which the lag-screws are inserted with elevated ribs or upwardly-projecting flanges C C2, thef arallel ribs C2 being located outside of and With the bearing-ribs c. The top sur aces of the ribs C C2 are located approximately 'in the same horizontal plane with the to surfaces ofthe outer margins of the baseanges a a of the raihand in such position with rev.spect to the spike-holes in the tie-plate that `when the screw-spikes areinserted into the ties through said holes with their heads or flanges d 'u1 bearing contacty with the railflangesy said heads or flanges will bear at their outer parts upon the top surfaces ofthe "said ribs C C2..

The advantage gained by the presence of the ribs C C2 on thetie-plate is that the outer parts of the heads or flanges of the screw-spikes are, when said spikes are tightened against the ,base-flanges of the rail, held up or supported by their contact with the bearing-shoulders lod formed by said ribs C C and -are thereby l rigidly retained in an upright position and held-from tipping or tllting outwardly at their up er ends, as is liable to occur when y tightening of the Aspike-heads against' the base-flanges of the rail in itself would tend to tip or tilt the spikes in the tie in such manner as to throw the u per ends of the spikes outwardly or away rom the rail, but when the said shoulders are present the spike-head has equal bearing at its ,inner part on the baseflange of the rail and at its outer part on the bearing-surface, so that the s ike retains its upright position when inserte and tightened and is held from assuming an outwardly-inclined position under outward pressureA of the rail or tielate thereon.

The ribs or anges C C2 are shown in Figs.v

1 and 2 as extending across the full width of the tie-plate but this cnstruction is not essential and is used on the tie-plate illustrated for convenience of manufacture in case of tieplates roduced lfrom a rolled blank, a long blank om which a number of tie-plates are to be-made being rolled to the cross-sectional shape shown in Fig. 1 and pieces of suitable length to form the individual tie-plates being then cut from the long blank in the manner ommon in the manufacture of tie-plates rom rolled blanks.

'In Figs. 3, 4, 5, and 6 I have shown modified constructions in wrought metal or rolled tie-plates wherein an elevation on the tieplate forming a supporting-shoulder located in osition to engage vthe head of the screwspi e at the side thereof opposite that which engages the base-flange of the rail isprovidedby means of an integral upwardly-bent ortion of the tie-plate itself. As shown in igs. 3 and 4, the tie-plate is provided outside of the hole c for the screw-spike' with two transverse cuts or slits forming a tongue C3, which is bent upwardly or into a vertical position and the upper end of which is disposed in the same horizontal plane with the marginal part of the base-flange of the rail. The

tongue 0 3 thus arranged forms a bearingshoulder ada ted to perform the same function as the li e bearing-shoulder lformed by the rib C or C2. (Shown in Fig. l.) In Fig. 5 and 6l I have shown still another modification .wherein the tie-plate C is provided with a tongue or projection C4, formed by the metal cutout `in forming the spike-holes 'c and bent upwardly into vertical position so that its top surface is in the same horizontal y plane with the top surface of the adjacent margin of the base-flange of the rail and is so located as to come beneath the external part of the screwspike head', as clearly .shown in Fig. 5.

vThe general features of construction heresurface of the base-flange of the rail.

inbefore referred to maybe applied aswell to a cast-metal tie-plate, andin Figs. 7 and 8 I have shown a construction wherein the tie-.

plateis provided with an elevated'part C5, located exterior to the spike-hole Iand extend- 'ing around the outer partl of lthesaid hole.

The top ofthe elevation C5 is made of proper height for contact with the under surface or shoulder of the spike-head when the latter comes in bearing against the base-flange of the rail, with the samevresults as hereinbefore set forth.

The downwardly-facing'shoulder formed I by the head or flange d of the screw-spike is y shown as made of conical form and inclined to correspond with the inclination of tlntlop en the said under surface of the spike-head is thus made of conical form, the bearing-shoul- .ders formed by the top surfaces of the supporting-ribs, lugs, or elevations on the tieplate willbe correspondingly beveled or inclined, as clearly shown in the several figures of the drawings, so that when the head of the screw-spike is tightened against the rail it will come to a. firm and solid bearing on said rib, lug, or elevation.

I claim as my invention- 1. A tie-plate provided at one side of the rail-seat with a rib forming an inwardly-facing bearing-shoulder for contact with the base-flange of the rail, with a hole for a screw-spike, and with an elevated bearingv outside of the spike-hole and separate from said bearing-shoulder, ada ted for contact with the head or flange of t e screw-spike.

-the under surface of the spike-head being inclined to correspond with the inclination of the top surface of the base-flange of the rail, and the up er surface of said elevated bearing being Vikewise inclined to. correspond with the under surface of said head.

3.
